Achieving a Sustainable Society
Toshihiko Baba Executive Operating Ofﬁcer

Nothing makes us happier than when we receive words of appreciation fromour customers, such as comments like “I’m so happy to use SANYO DENKI
products”!
This type of feedback motivates us as we pursue our corporate activities
throughout the world.

All of our three product brands, San Ace, SANUPS, and SANMOTION,
are designed for built-in use in customer equipment.
These products need to interface electrically and mechanically with theequipment they are built into.
For example, with our San Ace Cooling Systems products, cooling fans are
installed near the heat source of the equipment in which they are installed.
Also, these cooling fans are powered by the equipment’s power supply.
With our SANUPS Power Systems products, the output of uninterruptible
power supplies (UPS) provides the input power to the connected customer
equipment. This makes the electrical interface with the connected equipmenta very important component of these products.
With our SANMOTION Servo Systems products, servo motors provide
a driving force in the movable parts of the equipment in which they are
installed. Similarly, with servo amplifiers, electrical interface, to which motion
controllers are connected, plays an important role.
As these examples show, it is required for those products that are integrated
into other equipment to clarify their interfaces in addition to their internal
specifications.
To that end, it is necessary to understand the input/output specifications of
the connected customer equipment. That is, we need to “know our customers
better.”1

SANYO DENKI Technical Report No.53 May 2022

In other words, we have to work closely with our customers when designing
products.
The point is that we need to take a bird’s eye view of everything thatinvolves our products.

In October 2020, the Japanese government declared its goal of achieving“carbon neutrality” with virtually zero greenhouse gas emissions by 2050.
This defines greenhouse gas emissions, including CO 2 , as those from supply
chains. Supply chain emissions are classified as Scope 1 to Scope 3, and it isrequired to quantify the amount of emissions at each stage of a product’s life
cycle, ranging from the transportation of raw materials and production to use
and disposal of the product. The “carbon neutrality” initiative aims to reducegreenhouse gas emissions from business (Scope 1 and 2) to zero using carbon
offsets and other techniques. Moving forward, we will be required to quantify
and reduce greenhouse gas emissions that are not under our control (Scope 3:
indirect emissions other than Scope 1 and 2).
The point here is also that we need to look at the big picture of everythingthat involves our corporate activities.

We will push forward with various initiatives to work with our customers
throughout the world to help them overcome challenges and make theirproducts top in class. In addition, we will continue to promote corporate
activities that take into account the global environment and help realize asustainable society.
We believe that by vigorously promoting these activities, we will be able
to achieve “break the shell,” the primary goal of our 9th Medium-termManagement Plan.

1. Introduction
In recent years, residential ventilation systems haverequired fans that can blow air in two opposite directions
without much difference in noise and with high staticpressure. Generally, the human ear perceives large noiselevel differences as uncomfortable, therefore it is desirable
to make fan noise differences between the forward andreverse directions as small as possible. In addition, such
systems also require high static pressure of a fan to keep
ventilation airflow as constant as possible even when the airpressure changes between inside and outside.

1. Introduction
As the IT market continues to grow rapidly in recent years,
data processing equipment such as servers, storage devices,and routers has become increasingly sophisticated with highdensity and high-heat generation, requiring cooling fans witheven higher cooling performance. Furthermore, there is anincreasing demand to reduce power consumption as the world
moves toward a decarbonized society.
Fans with high static pressure performance are required
for such equipment. We developed and offered the San
Ace 60 9HV type High Static Pressure Fan in 2015, but
it has become obsolete and is unable to meet the latest

1. Introduction
The LAN Interface Card is an optional product for our
uninterruptible power supply (UPS). It comes with web
tools developed using the Java programming language thatenable users to view UPS status and measurement data as
well as perform the LAN Interface Card settings on a web
browser.
When we first developed these Java-based tools, the useof Java had the advantage of displaying screens with richfunctionality without being affected by differences in web
browsers. However, in recent years, an increasing number ofcustomers have requested a new tool that does not use Java

Fig. 1 LAN Interface Cardfor the following reasons:• Java vulnerabilities are frequently reported, and as such,there are concerns about security.
• To run an application developed in Java, a Java runtime

environment must be installed to the computer.
• Commercial use of Java is not free of charge anymore.

Our newly developed HTML-based web tool improves
convenience by integrating the functions of both the existingJava-based Web Management Tool and Web Display Tool.
By developing the application using HTML, we were able
to enhance security. In addition, it is now possible to send
and receive files, which had been difficult with the previous

The LAN Interface Card, when combined with our UPS,
can monitor the UPS operating status and automatically shut
down computers during prolonged power failures. Figure 1

3.3 User-friendly settings
One of the main features of the LAN Interface Card is its
ability to safely shut down computers in the event of a power
failure. However, the UPS operation settings for shutting
down a computer are complex and hard to understand forfirst-time users.
To it more intuitive, we created a “Simple setting wizard”“Statistical graphs” pageto navigate users through the configuration steps in an easy
and visual manner.
The “Simple setting wizard” navigates users through theconfiguration steps in order. This eliminates the chance ofsetting errors. In addition, by showing individual settings ina sequence diagram on the page, it makes it easier for firsttime users to understand the configuration items.

SA NYO DENK I contributes tosociety by developing new productsthat help enhance the performancea n d q u a l i t y of o u r c u s to m e r s’equipment and create new value.
This article introduces the featuresand innovations of the Ser vo
Systems products we developedin 2021 and describes how they
contribute to our customers andsociety.
These include stepping motors,
servo motors, and motion
controllers.
First, we have developed the
SANMOTION F 56 mm sq. 2-Phase
1.8° stepping motors, expanding
the product lineup of the series.
This product achieved a 4 0%
higher torque compared to ourconventional products by shortening
the air- gap length bet ween thestator and rotor and adopting amagnet with high residual magnetic
flux density. In addition, the noiselevel has been reduced by 3 dB by
optimizing component shapes andengagement method and increasingt h e m o to r r i g i d i t y. T h e m o to r
efficiency has also been improved
by 3% by increasing the winding fill
factor. With these improvementsin performance and characteristics,
the new product contributes to thedownsizing, energy savings, andnoise reduction of equipment.
Nex t , we developed a highl yreliable, compact, energyef fi c i e nt h o l d i n g b r ake fo r A C
servo motors. To improve brakereliability, we and a supplier jointly
developed a new friction plate andupdated the assessment criteriaof environmental durability. This
helped improving brake torquestability even in environments withsevere temperature and humidity
changes. The brake wear rate due
to idling wear has been reduced byhalf, further increasing reliability.
Moreover, we achieved downsizing
and lower p ower c onsumption
with a new structure where themotor and brake are integrated
into one unit and optimization ofelectromagnetic field. This new
holding brake c an improve thesafety and reliability of equipment,
as well as contribute to size
reduction and energy savings.
In the field of linear motors,
w e d e v e l o p e d a S A N M OTI O N
multi - axis integrated linear
ser vo motor unit. T his productachieves a high thrust thanks to
its optimized magnetic circuit.
The bobbin structure was devisedwith denser winding and reduced
copper loss, resulting in reduced
heat generation. In addition, we
designed the linear motion guiding
a p p ar atus to sup pres s fr ic tion
fluctuations during operation sothat the settling performance would

be more uniform. This product can
simplify the structure of customer
equipment thanks to its multi-axis
integrated design. With increased
thrust and improved settling
performance, it can also contributeto improving the performance andproductivity of those equipmentthat requires fast repetitive motion,such as surface mounters.
In the field of robot motion control,
we developed the SANMOTION C
S500 motion controller. This productcan control robots of various
configurations, including cuttingedge 7-axis articulated robots, andits robot communication cycle iseight times faster than that of ourconventional product. With a varietyof open networks supported, thecontroller can communicate with
network devices in real time andcan help make factories automatedand IoT-ready. In addition, the newcontroller has been downsized to
30% of the conventional product.
It features a much smaller size,
improves the per formance ofcustomer equipment, and helps

1. Introduction
In recent years, robots have been increasingly deployedin various industries to solve the labor shortage due to thedeclining birthrate and aging population in Japan. The
robot introduction into production processes has automatedproduction equipment and improved productivity throughlabor savings. To maintain high productivity with robots,
it is important to quickly detect and respond to changes
in the operating environment and production equipment

with which robots are used. Therefore, robot controllers
need to have advanced motion control functions as wellas information communication functions that can grasp
production status in real time and transform and transmit
relevant data.
To meet this need, we have developed a robot motion
controller that features various robot control functions, as
